CREASING AND SLITTING MECHANISM.

Application filed December 20, 1915. Serial No. 67,816.

To all whom t may concern.'

Be it known that l, CHARLES R. SEYMOUR,

a citizen of the United States, and resident of Rochester, in the countyof Monroe and State of New York, have invented'certain new and usefulImprovements in Creasing and .Slitting Mechanism, vof which thefollowing is a specification.'

The present invention has for its object to provide improved mechanismfor operating upon a web of material, such as lined corrugated board,paper board for making box blanks, or other similar materials. rlheoperations performed upon the web of material may be the formation ofcreases in the web, or slitting the web'longitudinally,

.or both, the specific character of the operations performed upontheweb'being dependent'upon the character or type of the elementsassociated with the mechanism for performing these operations.

The mechanism herein disclosed was designed especially for operatingupona web of lined corrugated board, but as will hereinafter appear,other materials than lined corrugatedv board may be operated upon justas efficiently. In the present instance, the mechanism is provided withcutting and crea-sing elements for providing the web with a plurality oflongitudinal creases and for slitting the.web longitudinally. Thecutting and creasing elements are rotary andare mounted upon two pairsof rotary mandiels or shafts, which, in turn, are arrangedin a verticalseries. Mechanism is provided for raising and lowermg the entire seriesof shafts to bring either pair into operative relation with the web ofmaterial so that the latter will pass between the shafts of such pair,and rhence between the cop- `eiating cutting and 'creasing elements onthese shafts. `While one pair of shaftsand the cutting and creasingelements thereon are being utilized for operating upon the web ofmaterial, the other pair of shafts are in their inoperative position.While two ofthe shafts with the cutting and creasing elements thereonarein their operative'position and operating upon the web of material,the cutting and creasing elements on the two shafts in the inoperativeposit-ion may then be adjusted for the succeeding 0rder, that is for themanufacture of a slitted and creased web having the creases andSpecification of Letters Patent.

probably the slits formedin the web along other lines. l

As above stated, the present mechanism i was designed for operating uponlined corrugated board and was designed especiallyY for use incombination with the machine disclosed in the co-pendin-g jointapplication of O. M. Hoch and m-yself, Serial No. 69,097, filed December28, 1915. The mechanism forming the sub-ject matter of the presentapplication is disclosed in the abovementioned 'co-pending applicationcombination with mechanism for performing certain other operations uponthe web, but is not claimed therein. It will be understood that thecutting and creasing mechanism herein disclosed isnot limited'l to usein com-` bination with a machine of the above-men;

tioned`character, but maybe used as -a unit by itself or in combinationwith any other mechanism necessary for performing other operations uponthe web.

The invention is illustrated in the accompanying drawings, in which:-

Figure l isa vertical longitudinal sect-ion through the center of theimproved slitting or cuttmg and creasing mechanism; and

Fig. 2 is a rear elevation, partly in section, of the improved cuttingand creasing mech` anism. y

Referring to the drawings, it will be noted that two pairs of shafts ormandrels are employed, the shafts of one `pair being ,shownat l and 1,respectively; and those of the other pair at 2 and 2, respectively. Eachpair of the shafts has positioned thereon, the elements for performing`the necessary operations upon the web. In the pres,- ent instance,creasing blades and slitting knives arc mounted upon the shafts, thecreasing blades `for the shafts 1 and l bein'g shown at 3, andthe-slitting knives for ,the/shafts l vand l being shown at 4. Likewise,the creasing blades for the shafts 2 and 2 are shown at 5, and theslitting knives for. the shafts 2 and 2 are shown at G. rlhe number ofpairs of slitting knives and creasing blades will depend upon the numberof places at which the web is to be slitted and the numberv of creaseswith which the web is to be provided. In the present instance, the pairsof slitting knives atthe extreme ends of theshafts are for the purposeof trimming the edge portions of the webfand the pai'rof knives shown atthe mid-portion of each pair of shafts is for the purpose of dividingvthe web longitudinally.- The creasing blades are provided in suficientvnumber, in the present instance, to provide th'e'web with two creases ateither side of the central slit. It is obvious that the exact arjVrangement of these elements upon the shafts is immaterial and the numberthereof may be decreased or increased, as desired. Furtherymore, it isnot even essential that the elements take the form of cutting andcreasing blades, because so far as the broad aspect'of invention areconcerned, it is immaterial what the specific character of the elementsupon the shafts happen tobe. v

Both pairs of shafts are mounted housings 7 and 8, which housings aremount'- ed for vertical' sliding movements in .Yth'eside frames 9 and10', respectively. The side` f rames 9' and' 10 may be supported in"" anyj suitable manner, such as upon the fra'iiienllvl of the machine incombination withwhie'h the present. cutting and creasing mechanism isused. Each side frame is providedlwith the guideway 12 in which thecorresponding housing is adapted to slide. Thespeciic manner o fslidably mounting the housings in the guides 12 is immaterial, but, inA

the present instance, eachof the housings-` is provided with gibs 13 and14, capable ofre-l taining the housings in -place withrespcct vto theframes 9 and 10 and the guideways 1 It is obvious that by turning theshaft 17,

the pinioiis 16 will rotate and either raise or lower the housings 7 and8 in the frames 9 and .10. This is for-the purpose of bringing one orthe other of the pairs of :Shafts into proper relation with the web ofmaterial, so that thesame will pass' between the shafts so brought intooperative position. In order to facilitate movement of the housings fromthe shaft17, links 19 may be ,pivoted to the lower portions vo f thehouspass between 'the shafts of the upper pair and hence, be operatedupon by the cutting and creasingcelements Aassociated with said shafts.'The Y'webmay be'fedto the shafts by. hand, if desired, orwhen thepresent cutting and creasing mechanism is associated 'with a machine forperforming other operati'oifi's upon the web, the feedingelements ofsuch machine may be depended upon to feed the web to the cuttingandvcreasing shafts. Fig. 1 shows-a discharge belt 21 `for conducting awaytheweb. Thisdischarge beltand the mechanism associated therewithconstitutes a portion of the machinedisclosed in the above mentionedco-pendingapplication. When either set or pair fof 'shafts is broughtinto operative position it is desirable to lock the housings 7 and 8 yinposition. This may be done by' providing a lockiiig pin 22 at each sideof the machine mounted in'the corresponding side frame.v These pins aremount-ed to slide longitudiupper pair of shafts is in the operativeposition, the extremities of the pins 22'are capable of engaging inopenings 24 formed in `the housings 7 and 8 to support or lock thehousings 7 and 8 in place, and when the flower pair of shafts is inoperative position, the extremities of said pins are adaptwise lock thehousings in position. It is `obvious that before-tlie housings canbemoved to change the position of the shafts, the pins 22 must bewithdrawn against the tension of the coil springs 23.

Means., is preferably provided foradjusting the distance between the twoshafts of each pair to either mo've the cutting and nally and are heldin their innermost positionby means of coil springs 23. When the'` y edto engage in similar openings-25' to likecreasing blades toward oraway'from each other. This may ber done by mounting the lowermost shaft1 of the upper pair and the uppermost shaft 2 of the lower pair inbushings 26, which, in turn, arev rigidly mounted in the housings 7 and8. r'The upper shaft l of the upper pair and the lower shaft 2 of thelower pair aremounted in 'I bearing boxes 27, which are capable ofsliding vertically in the housings 7 and 8. The two upper boxes 27 haveassociated therewith upwardly projecting hub portions 28 which areinternally threaded to lreceive a screw shaft 29. Each screw shaft 29 isrotated by means of a beveled gear 30 mounted thereon which meshes witha beveledpinion 31. The two beveled pinions 31 (Fig. 2) are mounted upona transverse ,shaft 32 supportedl by means of brackets 33 on thehousings 7 a'nd 8. The extremity of theshaft 32 ismsquared as shown at34; to receive a crank handle by means of which the shaft 32 may berotated' to simultaneously raise or lower the two upper bearing boxes27. vIt is obvious that the raising or lowering of 1. 'Lerares the twoupper bearing boxes 27 adjusts the distance between the shafts'l and -1of the upper pair.

A similar arrangement comprising screw shafts 29 engaging with thedownwardlyextending hub portions 28 of the' lower Abearing boxes 27serves to adjust the disceiving a crank handle to rotate the shaft.

By rotating the shaft 32', it is obvious that the lower boxes 27 will beraised or lowered to adjust the distance between the shafts 2 and 2 oft-he lower pair.

The shafts which carry the creasing lelements are positively rotated bymechanism designed so as not to interfere with t-he vertical movement ofthe shafts and-which is designed to positively drive the two shaftswhich happen to be in operative position. As shown in Fig. 2, a drivinggear 35 is provided'which may be driven in any appropriatemannerdepe'nding upon the relation in which the present cutting andcreasing mechanism is used. rlhe gem- 35 is mounted upon a stub shaft 36which also .carries a pinion 37, so'that the gear 35 and the pinion 37rotate in unison. The lowermost shaft of each pair, that is the shafts land 2', have secured thereto gears 3S and 39, respectively. The pinion37 and gear 35 are so positioned with respect to these gears 33l and 39that when the upper pair ofishafts.

is in the operative position, the pinion 37 wlill`mesh with the gear 38,and when the lowerpair of shafts is in operative position, the pinion 37will mesh with the gear 39. `When the gear 38 is rotated, the shaftl ispositively rotated and transmits motion to the shaft 1 through themeshing gears 40. Likewise when the gear 39 is rotated, the shaft 2imparts motion to the shaft 2 by means of the meshing gears 4l. It is,therefore, obvious that the two shafts of whichever pair happen to be inoperative position will be positively rotated from the pinion 37 and thegear 35.

lVhile one pair of shaftsand the cutting and creasing elements thereonare being utilized to operate upon the web, the cutting and creasingelements upon the other pair of shafts may be adjusted and re-positionedfor the next ob or order. 'In order to facilirtate the positioning ofthe elements upon the shafts, a gage or scale 42 is provided (Fig.

l) which runs longitudinally o`f the shaftsy and is supported onbrackets 4:3. Each-of the brackets 43 is mounted tov slide on and pivotabout the rod 44 carried by the housings 7 and S. The brackets 43 arenormally cutting and L42 adjacent to the cutting and creasing elementson veither of the intermediate shafts. When 'the scale is thus broughtinto close' relation with the cutting and creasing ele- `ments on eitherof the intermediate shafts, said elements may be properly spaced. Thecorresponding cutting and creasing elements on the coperating shaft maythen be spaced accordingly. 4

rIhe above-described double or duplex arrangement of the parts foroperating on the web of material -with means for bringing either set ofthe parts into operative relation may be applied to other machines thanmachines of the specific type herein disclosed. So far as this @featureis concerned, it is immaterial whetherthe operating `elements upon theshafts are cutting and creasing blades or lotherelements. Furthermore,various changes may be made in the details of constructionas abovedescribed without departing from the spiritor scope of the invention, asdefined in the accompanying claims. y 4
